Flightradar24 started as a hobby project in 2006 when two Swedish aviation geeks decided to build a network of ADS‑B receivers in Northern and Central Europe. In 2009 we opened up the network, and made it possible for anyone with an ADS‑B receiver to upload data to the network. Many parts of the world were quickly covered, but the quest to provide global ADS‑B coverage is still ongoing.
